Started my paranormal investigation journey about six months ago and quickly realised that EMF meters are either stupidly expensive or absolute garbage. So I bought three cheap ones and actually tested them properly instead of just waving them around a graveyard and hoping for the best.
Model 1: Generic Amazon EMF Meter (£18) Looks like a toy. Feels like a toy. Picks up literally everything - my kettle, my microwave, my neighbour's WiFi router. Not reliable for distinguishing actual anomalies. Skip this one.
Model 2: Meterk Digital EMF Detector (£28) Better build quality, actual screen, responds to EMF but also responds to everything. Bit less hair-trigger than Model 1. I've used this at a few locations and it's okay for basic work, but you're constantly second-guessing whether you've found something real.
Model 3: Trifield TF2 (£89) Proper equipment. Three-axis sensor, directional, actually consistent readings. I took this to Pendle Hill with my investigation group and it gave meaningful data that correlated with what people were experiencing. Worth the extra money if you're serious.
My recommendation: spend the extra £60 and get the TF2. You'll save yourself hours of frustration chasing false positives.
